Serial port vs. App window state
|
I have an "Irman" infra-red sensor connected to a serial port. This handy little device lets you use any hand-held remote control unit as a PC input device.
It also comes with an ActiveX control that makes program interface simple - an event "OnReceive" is triggered whenever a registered remote-control button is pressed.
I've just noticed that if I minimise the client application window, then remote control button events are not being responded to, but they seem to be queued, the OnReceive events only get triggered when the window is restored.
I'm not sure whether this is a bug/feature of this control, or perhaps there some more generic cause.
Any suggestions?
